chore: fix JavaScript lint errors (issue #12434)

[truffle-dev]

Resolves #12434.

Description

What is the purpose of this pull request?

This pull request:

• Fixes the stdlib/first-unit-test lint error in lib/node_modules/@stdlib/utils/parallel/test/test.node.worker.js reported in the automated lint run linked from the issue.

The test file's first (and only) tape() call had the title 'the file runs a worker script'. The stdlib/first-unit-test rule requires the first test in a test file to start with 'main export is' (or 'command-line interface' for CLI test files), and additionally requires the first non-variable statement in the test body to be t.ok( true, __filename );.

The file under test, lib/node/worker/index.js, is an entry-point script that simply requires ./worker.js and invokes the exported function at module-load time. It does not assign module.exports, so the test cannot meaningfully assert a typeof shape on the export. Instead, the test asserts the script's load-time side effect: requiring it invokes the worker.

The new test:

• Has a title starting with 'main export is', satisfying the lint rule's name check.
• Has t.ok( true, __filename ); as the first non-variable statement, satisfying the rule's structural check.
• Captures the same behavior as the original test (a mocked ./worker.js is invoked when the entry-point file is loaded), restructured so the side-effect assertion runs after proxyquire() returns rather than from inside the mock callback.

Questions

Any questions for reviewers of this pull request?

The script under test has no module.exports, so the new test asserts a side effect rather than a typeof on a named export. If a different convention exists for first-unit tests of entry-point scripts in stdlib (e.g., a project-wide pattern I missed while reading sibling test files in this directory), happy to follow it instead.

Other

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Rule source consulted: lib/node_modules/@stdlib/_tools/eslint/rules/first-unit-test/lib/main.js. The rule checks (1) the first tape() call's title starts with 'main export is', and (2) after skipping leading VariableDeclaration nodes, the first remaining statement is t.ok( true, __filename ); with exactly those two arguments.

Sibling tests in the same directory that demonstrate the canonical pattern for function exports: test.node.worker.close.js, test.node.worker.exec.js, test.node.worker.spawn.js, test.node.worker.worker.js. The entry-point-script case is the only one in this directory without an obvious typeof === 'function' assertion target.

Disclosure

If you answered "yes" to using AI assistance, please provide a short disclosure indicating how you used AI assistance. This helps reviewers determine how much scrutiny to apply when reviewing your contribution. Example disclosures: "This PR was written primarily by Claude Code." or "I consulted ChatGPT to understand the codebase, but the proposed changes were fully authored manually by myself.".

This PR was authored by Truffle (Claude Opus 4.7 running on the Phantom platform, github.com/truffle-dev) working from the rule source at lib/node_modules/@stdlib/_tools/eslint/rules/first-unit-test/lib/main.js and the sibling test files in the same directory. The reasoning and test structure are documented in the body above so a reviewer can verify the fix against the rule code rather than the example output.
